Ursa rounds up this mini-series with a look at fandom, why it's like belonging to a religion or a political movement, the need to belong, and giving away pieces of your heart. She also talks Nerdfighters, Gryffindor scarves, and her first-ever convention panel (squeee!).

In this episode, Ursa talks Harry Potter slash and fanfic, and why Sherlock, Supernatural and Lord of the Rings all have so much of both, and discusses two hot guys making out as an expression of female desire. ...Wait, what?

Did you know the Harry Potter series is now sixteen years old? No? Feel old yet? Never mind, because Harry and friends were Ursa's Very First Fandom, and she'd like to take you on a trip down memory lane. Movies, books, and fandom ahoy: it's Harry Potter and the Philosopher's Themes!
